Abstract (en)
[origin: WO2004097215A1] The invention relates to a rotor blade of a wind energy facility and to a wind energy facility. The invention aims at providing a rotor blade with a blade profile or a wind energy facility, which has an improved efficiency. To achieve this, several solutions are possible: rotor blade of a wind energy facility, wherein the rotor blade has a position of maximum thickness of approximately 15 % to 40 %, preferably from approximately 23 % to 28 %; the biggest thickness of the profile is approximately 20 % to 45 %, preferably from about 32 % to 36 %; the rotor blade has a two part configuration in the root area; a part of a rotor blade is configured in the outer side of the hub lining; the ratio between the profile depth of a rotor blade and the diameter of the rotor is approximately from 0.04 to 0.1 and the ratio between the depth of the profile of a rotor blade and the diameter of the spinner is between 0.5 and 1.
